Note: I originally wrote this article just prior to pressing pause on PublicBeta.
In hindsight - and reading this - I can totally see how obvious the things were that I was battling with at the time and how my own fears and uncertainties translated into questions like these.
That said though, I think there's something really valuable about this question and the way I at least tried to answer it back then.
Fact is that our own fear of failure and our perception of the things we do, causes massive self-doubt.
From experience, that self-doubt never goes away on its own and it's not an automatic process where you just magically feel more confident one morning you wake up.
Instead, you'll feel super-confident on Monday and super-shit on Tuesday by lunchtime. That's the nature of the beast.
But in answering this question in this way, I almost managed to dig myself out of the hole that I had found myself in.
How Do You Know This Is a Good Idea?
I'm sure that you have had this exact question (about your current project/pursuit/startup) as I have had: "Is this really a good idea?"
In the last couple of months, I've asked myself that question so many times about PublicBeta: Is it a good idea? Do I really see this working? Can I realistically believe that this can become a sustainable business?
Simply put, credit card details and actual revenues are always a sure sign that you are onto something. But in terms of really knowing (like you are 100% sure), that's probably not the silver bullet.
Instead I've been taking a more holistic view as to whether this thing I'm working on is actually a good (and potentially, sustainable) idea:
When I first wrote down that list, I looked at stuff like #1 & #2 above and felt that that was kinda obvious. But the rest wasn't that obvious; at least not on the surface.
There's something that should be said about (validated) traction that you can generate when the product (UI / UX) is still very painful to use. If people are willing to jump through hoops to a) pay you; and b) use your product, then surely the idea ain't half-bad.
